That’s not a real conclusion. You made that up, didn’t you? We never saw any of that.
Do you know how much stuff happens off screen in this show? Or because of magic handwaves Tons.Actual character development happens off screen! It’s about as plausible as saying Hook’s dead and has a tombstone in SB now because “he just died in the Underworld” (in spite of his very real appearance in that scene along with Little John who wouldn’t be there for Hook’s funeral)
Little John would be there for Emma’s sake. Remember how Rumple wasn’t there with belle when they were at a funeral for Jiminy Cricket who they thought was dead and murdered. Also we didn’t see Red, Pinocchio or Gepetto when they were at a funeral for Baelfire.
